A131 Prprofessional pH/ORP/Ion Meter

Professional benchtop ion meter contains 5 ion measurement modes, 2 to 5 points calibration. The meter is suitable for measuring the ion concentration and water hardness.

Ion Concentration Mode:
• Professional benchtop ion meter is equipped with a 7 inch TFT display.
• 2 to 5 points calibration, including the 8 concentration points can be selected.
• Electrode management is capable of storing and recalling up to 3 electrode slopes.
• Selectable ion measurement methods (direct reading, known addition, known subtraction,
  sample addition, sample subtraction) and concentration units (ppm, mg/L, mol/L, mmol/L).

Water Hardness Mode:
• 2 to 5 points calibration from low to high concentrations.
• Selectable measurement units (german degree, english degree, french degree, mmol/L
  and mg/L) are used for professional water hardness measurements.

Other Features:
• Automatic temperature compensation ensures accurate readings over the entire range.
• Auto-Read function senses and locks the measurement endpoint.
• Timed Interval Readings sends the measurement data to a PC or printer.
• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm prompts user to calibrate the meter regularly.
• Calibration report shows the date, time, calibration points and slopes.
• Password protection prevents the unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically resumes all settings back to the factory defaults.
